I know of a 360 racer with a heavy car that ran an 8 1/4" rear for a long time. But he switched to a Dana 60, which is very efficient and the overall weight can be removed elsewhere. I'm sure the switch was due to strength and parts availability.

I recall an article having the Dana 60 2nd to a 12 bolt in efficiency, and better than an 8 3/4. I don't believe the 8 1/4" was in the comparison, but Ford 9" was the worst.
